Type colon my keyboard?

I've tried making my robot print out colons but I just can't seem to.

I tried doing

Java Code:

            robot.keyPress(KeyEvent.VK_COLON);

and

Java Code:

            robot.keyPress(KeyEvent.VK_SHIFT);  
            robot.keyPress(KeyEvent.VK_SEMICOLON);

and neither seem to work, in fact I can't seem to get any symbols typed out (I don't want to copy to clipboard and paste out) (yes, I do keyRelease as well -> I've tried a bunch of stuff)
